I finally got the code for the check engine light last night and it says i need a Knock Sensor....The check engine light doesnt come on right when i turn the car on, it will come on about 10 minutes laters when im driving......what i want to no is, is the knock sensor expensive? and where is it located? is it hard to install?..........i have a 95 integra GSR..........my buddy told me it was in back of the block?.........thank you for your time

 

Yes its expensive, its right above the oil filter. A plus, any honda knock sensor will work, try and get one from ebay or a junk yard. I see a few on ebay right now.

 

It is a pain to change. This link will help you to plan a little:

they are kind of a pain with a stock intake manifold. it's not so bad if you have a skunk or blox manifold. you might need to drain your coolant a little bit. i just changed mine about two months ago. and yes they are expensive.
